90151235 divided by 33 
The aim is to understand the frequency of 33 in 90151235.

Going ahead to step 1:
When dividing 9 by 33, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 33

On to step 2:
33 goes into 90 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 66 from 90 leaves us with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 33

On to step 3:
If we divide 241 by 33, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 231 from 241 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 33

On to step 4:
105 divided by 33 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 273.0
Deduct 99 from 105 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 33

Going ahead to step 5:
61 divided by 33 is 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 2731.0
If we take 33 away from 61, we end up with 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 33

Going ahead to step 6:
282 divided by 33 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 27318.0
Deduct 264 from 282 and we're left with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 33

On to step 7:
33 goes into 183 5 times with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 273185.0
Deduct 165 from 183 and we're left with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 33

Moving on to step 8:
When dividing 185 by 33, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2731855.0
Subtract 165 from 185 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
33 can be fit into 200 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 2731855.6
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 33 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2731855.6
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 33, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 2731855.606
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
20 divided by 33 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2731855.606
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
33 can be fit into 200 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 2731855.60606
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 33 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2731855.60606
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
33 can be fit into 200 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 2731855.6060606
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 16:
